Information worth recording
Checklist · for your notes or inquiry
- Every visible mark, copied exactly as it appears, even if partly worn
- For watches: brand, model or reference if known, and whether it currently runs
- Approximate measurements, ring size or bracelet length if known
- Stones, as described in any documents, without guessing type or weight
- Condition: missing stones, bent prongs, worn plating, cracked crystals
Copy marks and numbers exactly as they appear, even if they are worn or you are unsure what they mean.
Keep facts, records and stories distinct
Observed
Copy exactly as seen
- Maker’s marks and purity stamps on clasps, inside bands and on reverses

Documented
Identify the existing record
- Original boxes and warranty papers
- Service and repair receipts

Reported history
Name the source, not a certainty
- Who told you the story?
- What did they say, and roughly when?
- Keep family recollections separate from records and visible details.
Not knowable from photos
Leave as open questions
- Photographs cannot confirm metal purity, stone identity or carat weight.
- Marks can be worn, misread, or applied to items that do not meet the standard they suggest.
- Watch authenticity, originality of parts and service history need physical examination.

- 05Keep any loose stones or links in a labeled envelope with the piece.
Brass strokes mark what to avoid or where to look.

Common questions
I have an appraisal from years ago. Is that useful?
Yes, as documentation of what someone recorded at the time. Appraisals for insurance are prepared for a different purpose than an auction and should not be treated as an expected sale price.
My watch does not run. Should I have it serviced first?
Not before talking to someone. Say whether it runs in your description; servicing decisions can come later.
Can you tell if a stone is a diamond from a photograph?
No. Stone identification requires testing.
